A Simple Thermodynamical Witness Showing Universality of Macroscopic Entanglement

Abstract:
We show that if the ground state entanglement exceeds the total entropy of a given system, then this system is in an entangled state. This is a universal entanglement witness that applies to any physical system and yields a temperature below which we are certain to find some entanglement. Our witness is then applied to generic bosonic and fermionic many-body systems to derive the corresponding "critical" temperatures that have a very broad validity. © 2009 World Scientific Publishing Company.
